Study on the utilization of phosphate solubilizing fungi and rock phosphate as a mean to increase corn yield was conducted in Kamphaengsaen soil and factorial in RCB with 3 replications, 5 isolates of fungi (control, KF2,KF7,KF9,RF33), 5 rates of rock phosphate (0,20,40,60,80 kg/rai) were carried out. The various isolates stimulated the corn to obtain higher yield than the control one, KF2, the highest effective isolate, stimulated the corn to have the highest yield as 623.0 kg/rai. Corn yields those stimulated from 20-80 kg/rai of rock phosphate were 527-587 kg/rai, but the control was only 462 kg/rai. In addition, the maximum yield of corn may be come from the combination of KF2 isolate and 80 kg/rai of rock phosphate that stimulated the plant to have the yield as high as 744 kg/rai.
